Greetings,
I want to get clarified on few things on selection piping metallurgy for the inlet of Reactor Effluent Air Condenser [REAC] for Hydro processing Units i.e Hydrocrackers & Hydortreaters.
1. Is anybody is using Austenitic Stainless steel [300 series] in these sections?
2. If yes,what is chloride content in the feed?
3. Above which threshold limit high nickel like Alloy 625, Alloy 825 or Duplex stainless steel is selected to avoid Chloride stress corrosion cracking?
